  • Specify compiler

CMake detects your compiler automatically but sometimes this is not what you want. In this case, you can specify the compiler by the following way,

  • Use the pre-built mptensor

TeNeS is based on the parallerized tensor library mptensor. The build system of TeNeS installs this automatically, but if you want to use the specific version of the mptensor, please add the following option in cmake.

$ cmake -DMPTENSOR_ROOT=<path to mptensor> ..
